RADIATOR-DISK..

Specification of Letters Patent.

Patented May 29, 1906.

Application lled October 17.1904. Serial No. 228,869.

T0 all whom t may con/cern:

Be it known that I, BENJAMIN BRIsooE, a citizen of the United States, residin at Detroit, in the county of Wayne and tats of Michigan, have invented certain new and useful Improvements in Radiator Disks, of which the following is a specification, reference being had therein to the accompanying drawing. f

The invention relates to radiating disks or flan es intended for increasin the amount of radiating-surface of the tu ular watercooler.

The invention consists in the peculiar construction of said disk, as ,hereinafter set forth.

It is essential in the construction of coolers of this type, first, that sufiicient radiatin surface be provided to disperse the heat, an secondly, that this radiating-surface should have a good conductin contact with the tube throu h which the ot Water is passed. It is also desirable that the radiatin disks or flan es should be properly s ace from cach ot 1er to permit of the circu ation of air therebetween and that they should be suflicicntly rigid to retain their shape. To fulfil these necessary conditions, my improved construction is one whichpermlts of the ar-4 rangement of a large amount of radiatin surface in a comparatively small space, eac radiating-disk being secured in position and adapted to permanently retain its shape, and a goodconducting contactbeang being rovided between each disk and the conduit.

In 'the formation of my .construction of radiator-disks, which I yhave shown in perspective in the accompanyin drawing, .a s eet-metal blank is fashioned by severin and stam ing at the central portion thereo so as to orm a circular aperture B with a segmental oints C, adapted to snugly fit t e outer surace of the Water-"conduit, such as D. Surrounding this central aperture B is a zone of 4 the disk which is radially corrugated, as at E, and. surrounding this is an annular bead or rib F'. This bead, together with the corrugations in the portion E, serves to stiffen the disk, so that it cannot be easily bent outof shape, while the segmental oints C hold the disk in a plane at right ang es to the axis of the conduit. The corrugations E and bead F also serve to increase the amount of radiating-surface within a given space, and, furthermore, by roviding a roughened surface over which t e air-current passes greater efficiency is obtained in dispersing the heat than by the use of a plane smooth surface.

Outside of the annular bead F the disk may be rovided with a circular corrugated portion i In o eration the heat ofthe Water passing throng the conduit D is conducted from the walls of said conduit rst to the points C and then to all portions of the surrounding disk. A. lurality of these disks are arrange in the Well-known manner in such relation to each other as to provide only a sufficient airspace between for the assage of the cooler and air-current, and t is in Atraveling over the corrugations and in striking against the annular beads will absorb the heat and carry it away. y

In order to further increase the efficiency of the radiator-disks, I preferably strike out the metal in the bead F at a series of points so as to form apertures through the disk, through which the air may clrculate and also projecting points against which the air. current will impinge in circulating between the disks, such a construction being illustrated in the drawing.

What I claim as my invention is- A radiator-fin com rising a sheet-metal disk having its centra portion severed and struck out to form bcarings'for engagement with the conduit, a crimped or corrugated zone surrounding the central aperture, a

bead surrounding said crimped or u corrugatedzone, the said bead having a series of apertures formed therein, the metal around said apertures being struck out to form projecting points.

In testimony whereof I affix my signature in presence of two witnesses. BENJAMIN BRISCOE.
